Introduction
The Italian Elevation Model - TINITALY - is a seamless digital elevation model that covers the territory of Italy. It is procuced by Tarquini et al and was first presented in 2007. The model is built from separate DEMS from each of the administrative regions of Italy. Grid resolution is 10m. This model is released from the National Institute of Geophysics and Volcanology / Istitutoi Nazionale di Geofisica e Vulcanologia (INGV).
As a part of the dataset evaluations by to Tarquini and Nannipieri [1], the authors found the TINITALY DEM to outperform other sources: The TINITALY DEM is currently the DEM having the highest resolution and the lowest error (on average) covering the whole Italian territory.... and it represents, at a country or (trans-)regional scale, a substantial step forward with respect to global DEMs such as the ASTER DEM and the SRTM DEM.... Please consult the references for further details.
Dataset Overview
- Spatial Coverage: Italian territory
- Resolution: 10 m grid
- Data-type: Digital Terrain Model (DTM)
- Coordinate system: UTM WGS84 - zone 32 (EPSG 32632) in original data
- Version: Data downloaded in September 2020.
- Vertical Accuracy: N/A
- No data value: -9999 (in original data)
Usage Notes
Higher resolution data exists for parts of the coastal areas: These 1m and 5 m gridded data may be accessed directly from the geodata-portal of Sardinia: http://www.sardegnageoportale.it
Availability from within WindPRO
The data are available directly from within windPRO in 10-meter grid resolution. The data can be accessed from the online-services in the following objects:
- Line Object (with purpose to height contour lines)
- Elevation Grid Object
